Here's a short video of our 13 tiger striped silver dollars in our 265 gallon tank. The dominant male, from Jeff Rapps, is the one with the black mask.
An update on my SD took this video couple months ago. My thinbars I think have maxed out at around 6". My Tigers I think are still growing the biggest ones are 5.5' mine are farm raised they have a tall body shape. About a year ago I had a disaster with a big water change lost 5 of my Widebars and lost some other fish so down to just 7 WB now,
